siggi's vs Chobani (2026): 17g vs 14g Protein Per Cup — Which High-Protein Yogurt Actually Wins?

The Quick Verdict

• Most protein per cup, plain vs plain: siggi's — 17g vs Chobani's 14g in the same 5.3oz cup.
• Best protein per calorie, plain vs plain: essentially tied — siggi's 17.0g per 100 cal vs Chobani's 17.5g per 100 cal.
• Most protein in a single cup, any line: Chobani — the High Protein 20g line reaches 20g, and the 30G ready-to-drink shake reaches 30g. siggi's tops out at 17g (plain) in its core cup lineup.
• Lowest calories for a meaningful protein hit: Chobani Zero Sugar — 60 calories for 11g of protein (18.3g per 100 cal), the leanest number either brand publishes.
• No artificial or non-nutritive sweeteners, in every single product: siggi's. Chobani's plain and High Protein lines also skip them, but its Zero Sugar line uses allulose, stevia, and monk fruit.
• Widest product range: Chobani — plain, Zero Sugar, High Protein 20g, Whole Milk, Flip, and two ready-to-drink protein shake lines. siggi's sticks to plain, flavored nonfat, a lower-sugar line, and a 2% line.
• Widest availability and lowest price: Chobani — sold at essentially every US grocery chain, typically priced below siggi's per cup.

Plain vs Plain: The Core Comparison

Both brands' flagship product is the nonfat plain cup, and it's the fairest single comparison since neither has added sweetener of any kind.

The two are closer than the headline numbers suggest. siggi's wins on absolute protein per cup (3g more), but Chobani's lower calorie count means the two are essentially tied on protein density — 17.0g vs 17.5g per 100 calories, a gap too small to matter for most people. Both use the same short ingredient list philosophy for their plain cups: cultured milk and live cultures, nothing else. The practical difference comes down to texture (siggi's skyr straining produces a noticeably thicker, denser cup) and calorie budget (Chobani's 80 calories vs siggi's 100).

Full Lineup Comparison

Past the plain cup, the two brands stop looking alike. Here is every major line from each, side by side.

A few things jump out. Chobani's High Protein 20g line beats every siggi's cup on absolute protein (20g vs siggi's max of 17g). siggi's Lower Sugar Vanilla and Chobani Nonfat Plain land on the exact same protein-per-calorie ratio (17.5g per 100 cal) despite different formulations. And Chobani's Flip line isn't really a competitor on protein terms at all — it's a dessert-style snack that happens to contain yogurt, not a protein-first product; siggi's has no equivalent treat-style line.

Beyond the Cup: Chobani's Ready-to-Drink Shakes

The biggest structural difference between the two brands is that Chobani has expanded into bottled, ready-to-drink protein shakes — a category siggi's doesn't compete in at all. Chobani's 20G High Protein Greek Yogurt Drink delivers 20g of protein with 0g added sugar and is lactose-free; the 30G line delivers 30g of protein in a 14 fl oz bottle, also lactose-free with 0g added sugar, putting it in the same protein bracket as Fairlife Nutrition Plan and Premier Protein. Both drink lines are made from ultra-filtered Greek yogurt rather than added protein powder or concentrate. If a grab-and-go bottle matters as much as a spoon-and-cup format, Chobani is the only one of these two brands with an answer.

Sweeteners: The Real Philosophical Difference

This is where the two brands actually diverge, not just on a spec sheet but in stated philosophy. siggi's uses zero non-nutritive sweeteners in every single product it sells — no stevia, no sucralose, no allulose, no erythritol, no monk fruit, no aspartame. Plain cups carry no sweetener at all; flavored cups use only cane sugar or, in the lower-sugar line, a small amount of organic agave nectar. That commitment traces back to the brand's founding in 2004, built explicitly against the artificial-sweetener-heavy US yogurt market of the time.

Chobani is more mixed. Its plain, Whole Milk, and High Protein 20g lines also use no non-nutritive sweeteners — the High Protein line leans on ultra-filtered milk's natural sweetness and fruit alone. But the Zero Sugar line specifically uses allulose, stevia leaf extract (reb M), and monk fruit extract to hit 0g total sugar at 60 calories. Both companies' 2025-era ready-to-drink shakes (Chobani's 20G/30G lines) carry 0g added sugar, though siggi's has no drink format to compare against.

The practical takeaway: if avoiding every non-nutritive sweetener across an entire product line is non-negotiable, siggi's is the safer default purchase — you don't have to read the label on every cup. With Chobani, the plain and High Protein cups are sweetener-free, but picking up a Zero Sugar cup by mistake means picking up allulose and stevia.

Where Each Brand Wins

Pick siggi's if…

• You want the highest absolute protein in a plain cup (17g) and a guarantee that nothing you buy from the brand contains a non-nutritive sweetener.
• You prefer a thicker, denser, more traditional skyr texture over a looser Greek yogurt texture.
• You're comfortable with real cane sugar in flavored cups (7–9g added) as the trade-off for avoiding stevia, sucralose, or allulose.

Pick Chobani if…

• You want the widest range of options under one brand — a near-zero-calorie Zero Sugar cup, a 20g High Protein cup, a treat-style Flip snack, and ready-to-drink 20g/30g protein shakes.
• You want the single lowest-calorie option either brand sells — Zero Sugar at 60 calories for 11g protein.
• Wide grocery availability and lower per-cup pricing matter more than brand-wide sweetener purity.
• You want more protein than either brand's plain cup offers without switching brands — the High Protein 20g line or the 30G drink both beat siggi's ceiling.

Frequently Asked Questions

Which has more protein, siggi's or Chobani?

Plain cup vs plain cup, siggi's has more absolute protein (17g vs 14g in the same 5.3oz serving). But Chobani's High Protein 20g line (20g per 6.7oz cup) and 30G ready-to-drink shake (30g per 14 fl oz bottle) both beat anything siggi's currently sells. On protein density (grams per 100 calories), the two brands' plain cups are nearly tied at 17.0g (siggi's) vs 17.5g (Chobani).

Does siggi's or Chobani use artificial sweeteners?

siggi's uses none in any product — plain cups have no sweetener, flavored cups use only cane sugar or organic agave nectar. Chobani's plain, Whole Milk, and High Protein 20g lines also use no non-nutritive sweeteners, but its Zero Sugar line uses allulose, stevia leaf extract, and monk fruit extract to reach 0g total sugar.

Which is better for weight loss, siggi's or Chobani?

Chobani Zero Sugar is the lowest-calorie option either brand offers (60 calories, 11g protein), which suits a tight calorie budget. For a better protein-to-calorie ratio without any sweetener at all, siggi's Lower Sugar Vanilla and Chobani Nonfat Plain are tied at 17.5g protein per 100 calories. See our best high-protein snacks for weight loss guide for the wider field.

Is siggi's skyr the same thing as Chobani's Greek yogurt?

Not technically. siggi's makes Icelandic-style skyr, a strained cultured dairy product; Chobani makes Greek yogurt, a strained yogurt. Both go through a similar straining process to concentrate protein and remove liquid whey, which is why their nutrition profiles land in a similar range, but they are different dairy categories with slightly different cultures and traditional preparation methods.

Which brand has more product variety?

Chobani, by a wide margin. Beyond plain and flavored cups, Chobani sells a Zero Sugar line, a High Protein 20g line, a Whole Milk line, the dessert-style Flip line, and two ready-to-drink protein shake lines (20G and 30G). siggi's lineup is narrower: plain, flavored nonfat, a lower-sugar line, and a 2% milkfat line — no drinks, no dessert-style products.

Which is cheaper, siggi's or Chobani?

Chobani is generally the lower-priced option per cup and is more widely available across US grocery chains. siggi's typically carries a modest price premium, consistent with its smaller product range and no-non-nutritive-sweetener positioning. Exact pricing varies by retailer and region.

Bottom line: Plain cup vs plain cup, siggi's and Chobani are nearly tied on protein density (17.0g vs 17.5g per 100 calories) — siggi's just packs it into fewer, denser calories per gram of protein while Chobani spreads a wider net across Zero Sugar, High Protein 20g, Flip, and ready-to-drink shake lines. Choose siggi's for the highest plain-cup protein and a guarantee against every non-nutritive sweetener; choose Chobani for range, availability, price, and a genuine 20g-plus option.
